		In this document use of Georgian language package for \TeX{}/\LaTeX{}
		is described.
	\end{abstract}
	\section{Installation}
	For package installation \TeX{} distribution must be installed. This can be 
	{MikTeX} or {TeXLive} Windows OS and TeXLive for Linux/Unix and MacOSX 
	systems. It is not necessary, but it is better to have
	local \TeX{} directory. For Linux/Unix systems you can use 
	\verb|$HOME/texmf|
	See your \TeX{} distribution documentation for more detailes.
	\subsection{Using MikTeX}
	\begin{itemize}
		\item  Install MikTeX \verb|http://miktex.org| .
		\item Since April 2015 MikTex includes packages: "georgian-babel" and 
		"georgian". Install them Using  MikTex package manager.
	\end{itemize}
	\subsection{Using TexLive}
	\begin{itemize}
		\item   Create local  \TeX{} directory. 
		\item Download GeoTeX  \verb|http://tex.tsu.ge|  and install it in local \TeX 
	\end{itemize}
	\subsection{Automatic hyphenation}
	Automatic hyphenation works. \verb| hyph-utf8| is already included in TexLive. 
	For MikTex download  \verb| hyph-utf8| and install it in localtemf tree.
	Copy 'languages.ini' file to MikTex's config directory. Do update formats
	from MikTex's settings manager ('User' and 'Admin' modes ).
	After this system must know about Georgian hyphenation.
	\section{The First Steps}
	After package installation user can write documents in Georgian. For this can 
	be used any
	plain text editor, but there are \LaTeX{} suitable Integrated Developing 
	Environment (IDE)
	Editors , such as 
	Texmaker \url{www.xm1math.net/texmaker}, TexStudio  Texmaker 
	\url{http://texstudio.sourceforge.net}, TeXnicCenter  
	\url{http://www.texniccenter.org},
	WinEdt  Texmaker \url{http://www.winedt.com}.
	
	Note, that Georgian input text must be in utf-8 encoding.
	
	There are three basic classes in \LaTeX{} : Article , Report , book.
	Minimal document has a following form:
	\begin{verbatim}
	\documentclass[a4paper]{article}
	\usepackage[T1,T2A,T8K,T8M]{fontenc} %use English, 
	%Russian, Georgian fonts
	\usepackage[utf8]{inputenc} %Text Encoding
	\usepackage[english,russian,georgian]{babel} %Document's 
	%language is Georgian
	\begin{document}
	Document text
	\end{document}
	\end{verbatim}
	For languages based on Georgian script (Megruli,Laz,Chan,Svan), which use
	umlauts and accents we can use  \TeX functions. Fox example:\\
	{ \Georgian
		\'{ა} \.{ა} \H{ა} \`{ა} \"{ა}  \^{ა} \d{ა} \~{ა} \u{ა}  \={ა} \v{ა} \t{აბ} \\
	}
	Because of Georgian script don't fit in one encoding, two encodings T8M and
	T8K-Asomtavruli-Mkhedruli and   Khucuri-Mkhedruli are 
	introduced\footnote{see . kaencodings.pdf for detailes}.If we turn on  
	\emph{\bfseries amsmath} package, 
	We can have following text: 
	{\Georgian
		$\bar{\text{ა}} $, 
		$\overset{\text{ა}}{\text{ბ}} \text{უ}^{\text{ბ}}$.\\
	}
	The \emph{{\bfseries babel }} package knows about Georgian and the most
	therms are translated. \emph{{\bfseries babel }} loads   T8K , and then  T8M 
	encoding definition files. This means, that main encoding of the document will 
	be
	T8M (Asomtavruli-Mkhedruli). If user needs to have basic encoding T8K 
	(Nusxkhuri-Mkhedruli), than in document's preamble must have
	\begin{verbatim}
	\usepackage[english,georgian]{babel}
	\usepackage[T8M,T8K]{fontenc}
	\end{verbatim}
	In such document text can be in Nuskhuri-Mkhedruli script without any 
	additional
	command and for Asomtavruli script user needs:
	{\Georgian \mrglovani
		\begin{verbatim}
		\mrglovani
		მაგალითად
		{\mrglovani ასომთავრული ტექსტი ႠႱႭႫႧႠႥႰႳႪႨ }
		\end{verbatim}
	}
	{which gives: \mrglovani ႠႱႭႫႧႠႥႰႳႪႨ }
	\\
	If document's encoding is T8M, than before Nuskha-Khucuri script we need:
	{\Georgian
		\venc{T8K}
		\begin{verbatim}
		{\khucuri   ხუცური ტექსტი ⴞⴓⴚⴓⴐⴈ ⴒⴄⴕⴑⴒⴈ}
		\end{verbatim}
	}
	Which gives: {\Georgian \khucuri   ⴞⴓⴚⴓⴐⴈ ⴒⴄⴕⴑⴒⴈ}
	
	This is necessary, because Nuskhuri and Asomtavruli are defined in different 
	encodings.
	\section{Text indexing}
	\TeX{} uses $makeidx$ and it works for Georgian scripts, but output
	file is in \TeX's internal representation(in therms of macro commands) not in 
	utf-8 and hard
	to read. For UNICODE texts is the best suited \emph{xindy} package and 
	works for
	Georgian scripts, but it is not
	available for \emph{MikTeX} distribution. But we can use
	\emph{index} and \emph{idxlayout} packages to have nice output.
	Add in the preamble:
	{\Georgian
		\begin{verbatim}
		\usepackage{index}
		\usepackage[columns=3,totoc=true]{idxlayout}
		\newcommand{\Index}[1]{\index{#1}#1}
		\makeindex
		\renewindex{default}{idx}{ind}{საძიებელი}
		\end{verbatim}
	}
	In this way we can index words in the document on following way
	{\Georgian \verb|Index{სიტყვა}| }.To add index page in the document one can 
	use \verb|\printindex}| in place of desired output of index page. But this is not 
	enough. After indexing
	document do:
	\begin{verbatim}
	makeindex.exe    "filename".idx
	\end{verbatim}
	$filename.idx$ is created after Build command User can also pass the style file 
	(for example. $latex.ist$)
	and after this we need to rebuild document again.
	\section{Nomenclature (Definition of therms and symbols)}
	Add in the preamble:
	{\Georgian
		\begin{verbatim}
		\usepackage{nomencl}
		\makenomenclature
		\renewcommand\nomname{აღნიშვნები}
		\end{verbatim}
	}
	After file compilation do
	\begin{verbatim}
	makeindex <filename>.nlo -s nomencl.ist -o <filename>.nls
	\end{verbatim}
	and rebuild file again. Of course there need to be \verb|\printnomenclature|  in 
	the document, where you need nomenclature to be printed.
	\section{Fonts}
	T8M and T8K encoded   fonts are based on: DejaVu fonts 
	\url{http://dejavu-fonts.org}
	and other  avialable Georgian free fonts and can be distributed freely.
